Stalon XL Extension by Hilleberg is a modular extension for a Stalon XL Basic tunnel tent. With 145 cm in width, it provides plenty of additional space. You only need to zip it to your existing modules, so if you wanted, you could also go ahead and join a dozen extensions together! The extension module has two separate entrances and is made from highly robust Kerlon 2000, which is the strongest material Hilleberg uses for outer tents. ;"""
